HORSESHOEF SPECIFICATION forming part of Letters Patent No. 271,307, dated January 30, 1883., Application filed December 4, 1882. (No model.)

To all whom it may concern:

Be it known that I, GOTTHARD BRANDL, of Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Horseshoes and I do hereby declare the following to he a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

This invention has for its object to improve the construction and mode of application of horseshoes; and it consists in certain details of construction and combinations of parts,which will be first described, and then pointed out particularly in the claims at the end of this specification.

In the drawings, Figure 1 represents a perspective view of a horseshoe constructed and applied in accordance with my invention. Fig. 2 is a crosssectional view of the same. Figs. 3 to 8, inclusive, represent detail views of the devices for securing the shoe to the hoof, and Figs. 7 to 18 represent detail views of modifications of the securing devices.

Similar letters of reference in the several figures denote the same parts.

A represents a shoe constructed of steel, malleable cast-iron, red brass, or other suitable material, and provided on its upper face with a rest or hearing for the footof the horse, preferably channeled or grooved, as shown at a a, and with an upwardly-projecting flange, a, adapted to inclose the edges of the horses hoof, prolongations f of said flange being formed at several places thereon to better effect this object. The channels or grooves a are intended to be filled with grease and some porous substance-such as cloth, felt, or other equivalent material-to prevent brittleness of the hoof, and the metal of the shoe between the channels is preferably brought to an edge, to further insure a firmer connection between the hoof and the shoe. The flange a. of the shoe not only serves, in connection with the channeled or corrugated portion, to effect a firm connection between the hoof and the shoe and prevent lateraldisplacementof the latter, but also operates to,i n a measure, prevent the escape of the grease from the channels.

A dovetailed groove is formed in the under side of the shoe, and fitted within such dovetailed groove, and preferably secured by suitable cement, are the corresponding portions of elastic bearing-pieces G D l), of rubber, guttapercha, rope, leather, teak-wood, or other suitable equivalent elastic material.

The shoe is further provided with suitable toe-calks, B and O, and heel-calks B, these calks being made preferably of cast-steel, and secured to the metal part A of the shoe by screws passing down into them through the shoe A from above, or by screws passing upward through them and into the shoe A, with their heads countersunk, or by-pins or other suitable fastenings.

The adjoining elastic sections may be separated by metal plates b b, as shown in Fig. 1, or mayabut against each other, as desired.

The groove in theunderside ot'the shoe extends entirely around it, and the calks, as well as the elastic bearing-pieces and the-plates I) b, are applied at the ends of the grooves and slipped into place, as will be readilyunden stood.

The shoe thus constructed may be secured to the hoof of the animal by the following means: Referring to Figs. 3 and. 4,13 represents a steel plate, having an opening, e, passing through it, terminating in an enlarged 8o countersunk recess, 6, at the back, as shown in Fig. 4, and having one or more backwardlyprojecting points, e Over this plate E is placed another steel plate, H, having an opening, h, through it, terminating in an enlarged countersunk recess, h, at the front, as shown in Fig. 8, and having also through it an opening, 2'. and an elongated slot, h

F, Figs. 5 and 6, represents an eccentric, having a pin, (1, adapted to pass through the 0 opening 6 of the plate E, aportiomf, adapted to pass through the opening it in the plate H, and a portion, f adapted to tit the countersunk recess h in front of the plate H. In putting these various parts together, plate H is placed upon the plate E, and the eccentric F is inserted in position in plate H, with its pinf projecting through the opening 6 in plate E, and a head, f fitting the countersunk recess 6, is secured to the end of the pin fin any suitable manner. The complete device is then ready for application to the hoof of the ani-' mal and its shoe, and the application is effected by driving the points e of the plate E into the hoof, and securing the plate H to the metal portion A of the shoe by means of a screw, G,

'2 sensor 7 passed through the slot h shoe A, as shown in Fig. 1. By turning the eccentric F, by means of a screw-driver applied to a nick in its outer face, the plates H v E will be caused to slip on each other, and to consequently draw the shoe and the hoof tightly together, the eccentric being locked in position by means of a screw passed through the opening '5 in plate H, and engaging with a recess, f, in the edge of the eccentric. The plate H is preferably recessed into the metal shoe A in order to be flush with the surface thereof. I have found from experience that four of these fastening devices,'applied two at the front and one at each side of the hoof, prove sufficient but a greater or less number may be used, if desired.

The fastenin g devices are susceptible of many modifications. For instance, as shown in Fig. 8*, the plate H may be provided at its lower end with a toe or projection, W, and fitted to one or the other of a series of recesses formed in the metal shoe A; or said plate H may be provided with a cross-bar at its lower end of circular form flattened on one side, as shown in Fig. 8", and the shoe A may be provided with a recess corresponding to the circular portion of the cross-bar, so that the cross-bar, when the plate H is turned down, can enter the recess in the shoe A, and then, when said plate is turned up again, will be prevented from working out of said recess, as will be apparent from an inspection of Fig. 8

Another modification is shown in Figs. 9, 10, and 11, wherein a plate, T, haying a dovetailed lower end, is set into a corresponding recess in the metal shoe, as shown in Fig. 14, and a metal plate, 70, having points or prongs for attaching it to the hoof, is made to co-opcrate with said plate T and with an eccentric, F, whose pin f is held stationary within the plate It, while its eccentric head, when turned, co-operates with the portion f of theplate T, and causes said plate T to be raised or lowered with respect to plate It, as will be readily understood. When plate T is raised, as shown in Figs. 9 and 10, a projection, t, on plate It engages with a corresponding recess, t, in said plate and holds the plates firmly locked. Instead of dovetailing the lower portionof plate T into the metal part of the shoe, said lower portion may be formed with a hook-shaped projection, L, as shown in Figs. 12 and 13, adapted for engagement with the corresponding part of the shoe.

In another modification, (shown in Figs. 15 and 16,) a trapezoidal plate, M, is slipped from below into a corresponding recess in the shoe and arranged to co-operate with an eccentric, F, whose eccentric pin is supported in a plate, N, held to the boot by points, as shown. The periphery of the head of the eccentric is provided with a series of semicircular recesses, n, which co-operate with screws a, screwed into the plate M. These screws n have aflattened portion, W, as shown in Fig. 17, and when they are turned with their flattened portions and into the metal I toward the eccentric the latter can be turned until its recess it comes opposite the screws, and then the turning of the screws will cause the threaded portion thereof to engage with the recesses and hold theeccentric rigidly in position, as will be readily understood.

A somewhat less complicated arrangement than that shown in Figs. 15 and 16 is shown in Figs. 17 and 18, where the eccentric disk secured to the plate N, asin Fig. 16, is caused to turn in a'depression orrecess made directly in the body of the shoe, instead of in the plate attached to the shoe.

It will be apparent that horseshoes constructed in accordance with my invention can be very easily and quickly applied by any one having the slightest mechanical skill and without the necessity of employing a blacksmith for the purpose; that the manner of securing the shoes does not. break or injure the hoof and tend to the production of hoof-diseases, as does the ordinary mode of applying shoes; and that the elastic portions of the shoe preshocks ordinarily incident to travel over hard surfaces, and also that the animals feet are effectually prevented from slipping.

Having thus described my invention, I claim as.new

1. The metal shoe provided in its upper surfacewith the grooves or channels, and having the upwardly-extending peripheral flange, substantially as described.

2. The metal shoe having the dovetailed groove in its under side extending entirely around it, in combination with the metal calks and the elastic hearing portions (J D D, all having dovetailed parts corresponding to the grooves in the metal shoe, substantially as described. i

3. The combination of the metal plate secured by prongs to the hoof df-the animal and an eccentric co-operating with the metal shoe and said plate, to bind the shoe to the hoof, substantially as described.

4. The combination of the metal shoe, the

plate secured to the hoof, the plate secured to the metal shoe, and the co-operatin g eccentric, substantially as described.

5. The combination of the metal shoe, the plate attached to the shoe, the plate connected to the hoof, the eccentric co-operating with said plates, and the means for. locking the eccentric, substantially as described.

6. The combination of the metal shoe, the metal plate adjustably connected to the shoe, the plate attached to the boot, and the eccentric, the whole constructed and arranged substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
